Oh, I love these speakers! Tired of moving with them at 48lbs. They are loud enough to not to hear the person next to you. I actually took a competition car stereo bass cd and warped the sliding door almost breaking glass. It also about blew out the rear bedroom window, now that is some sound pressure. I was using a Pioneer at 110w per channel now it died along with the center channel. Lots of distortion in Doom DVD, but well worth the earthquake surround. I am looking at new pioneer digital amps

I recently seen Tangent 500s for sale on ebay. I was looking to down size myself and was wonedering what my 400s are worth. If I upgrade is the cost of selling these off worth the new price to power? My center experinced a meltdown and my Pioneer quit on me so I would be in the market for new stuff.
